Chapter 1 - Introduction
Congratulations on your purchase of the Multi-Tech MT5656ZDX-Series modem.
●
The Multi-Tech MT5656ZDX modem is your data/fax modem.
●
The MT5656ZDX-V offers your voice option.
You have acquired one of the finest intelligent data/fax or voice/data/fax modems available today from one of the
world’s oldest modem manufacturers: Multi-Tech Systems, Inc. This user guide will help you install, configure,
test, and use your modem.
Product Description
The Multi-Tech MT5656ZDX and MT5656ZDX-V modems are compatible with the ITU-TV.92 protocol that
provide quick connections, downstream transmissions at speeds up to 56K bps, and upstream transmissions at
speeds up to 48K bps when connected to V.92-compatible Internet Service Providers. The V.92 protocol is
able to send downstream from the Internet to your computer at these speeds because data on the telephone
network typically is converted from digital to analog only once before it reaches your modem. Upstream
transmissions and transmissions between client modems are limited to 33.6K bps, as are upstream
transmissions that are converted more than once on the telephone lines.
Modem features include Plug and Play operation. In standard mode, the modem can store up to four command
lines or telephone numbers of up to 40 characters each in nonvolatile memory. Other modem capabilities include
modem-on-hold, AT&T calling card tone detection, pulse and tone dialing, adaptive answer, V.42bis and V.44
data compression, and self-resetting lightning protection.
Please note that some V.92 features are turned off in the factory default configuration, and may need to be
turned on, depending on your needs.

Multi-Tech Systems, Inc. MT5656ZDX User Guide
Chapter 2 - Hardware Installation
Connect the Power
Make sure the power switch is set to OFF. The power switch is located on the side panel of the modem.
Plug the power supply into a power outlet or power strip. Plug the other end into the PWR jack on the
modem.
CAUTION: Use only the power supply cable supplied with the modem. Use of any other power supply voids
the warranty and can damage the modem.
A Note About Power Connection, Surge Protectors, and Lightning
Power surges and other transient voltages on power lines, such as those caused by lightning
strikes, can damage or destroy your modem. Therefore, we recommend that you plug the modem into
a surge protector rather than directly into a wall outlet, preferably a surge protector that provides
protection against electrical spikes on the phone line as well as on the power line. Note that not even
a surge protector can guard against damage from a nearby lightning strike. During an electrical
storm, it is safest to unplug your computer equipment from both the power outlet and the phone line.
Power-On Test
Test the modem by turning it on (an on-off switch is located on the side panel). When you apply
power, the modem performs a diagnostic self-test. The PWR indicator lights; and if a terminal program is
running, the TR indicator also lights. If this does not happen, check that the power switch is on, the
power supply is solidly connected, and the AC outlet is live. If these measures do not work see the
Troubleshooting chapter.
Note: The Federal Communications Commission (FCC) and Industry Canada impose certain
restrictions on equipment connected to public phone systems. For more information, see Appendix
A.

Voice Connections (Voice option only)
Voice Connections for Voice Models
(Optional) Connect the Modem to the Phone
For voice-only calls, plug a phone into the modem’s PHONE jack.
Connect the Microphone
For voice mail or speakerphone applications, plug an unamplified microphone into the MIC jack on
the side of the modem. The microphone should have a stereo 1/8-inch (3.5mm) mini plug. Do not use
a monophonic microphone.
Connect the Speaker
For speakerphone or voice mail applications, use a 1/8-inch (3.5mm) plug male-to-male stereo
patch cord to connect the SPKR jack on the side of the modem to the LINE IN jack on your sound
card. If your sound card does not have a LINE IN jack, use its MIC jack. The stereo male-to-male
patch cord can be purchased at a local PC retail store.
If you do not have a sound card, you can plug an amplified speaker directly into the SPKR jack.

Installing the Modem Driver
If you use Windows 2000 or newer, you must install the modem driver. If you use another operating system, see
Appendix B.
When operating the modem under Windows, the modem driver can be installed by using the Plug and Play
feature. Follow the procedure below.
1. Make sure your modem is connected properly, and then turn on your computer. Windows should
detect your new modem and open the Welcome to the Found New Hardware wizard.
Note: If Windows cannot find a modem, your modem may be turned off, or it may be plugged into the
wrong connector on your computer. See “Troubleshooting” in the User Guide.
2. From the Browse function in the Install Wizard, point to the Temporary folder you created on your local PC
to store the driver that you downloaded from the Multi-Tech website.
3. Windows installs and configures the modem.
4. Click Finish to exit.

Chapter 2 - Hardware Installation
Connecting to the Internet
Your Multi-Tech modem is your gateway to the Internet and the World Wide Web. To access the Internet and Web
via your modem, you must establish a dial-up account with an Internet service provider (ISP). To locate an ISP
near you, look in a local directory or computer publication. Your ISP should provide you with the following
information:
●
User name (also called user ID)
●
Password
●
Access number (the number you call to connect to the server)
●
Host name and/or domain name
●
Domain Name Server (DNS) server address
If, besides the Web, you use the Internet for email and newsgroups, your ISP should also provide you with the
following information:
●
Email or POP mail address
●
POP server address
●
Mail or SMTP address
●
News or NNT server address
Dial-Up Networking
Before you can connect to the Internet, you must set up a remote-node client program on your computer. The
Windows version is called Dial-Up Networking. Dial-Up Networking establishes your connection to the ISP’s server,
which is the shared computer that manages calls from clients (your computer) to the Internet. Most, if not all,
Windows browsers start Dial-up Networking automatically when you open them.
For instructions on how to set up Dial-Up Networking, consult your ISP or your operating system’s online help or
printed documentation. Many ISPs include with their service a program that will instruct and configure Dial-Up
Networking automatically for you.

Multi-Tech Systems, Inc. MT5656ZDX User Guide
Chapter 3 - Operation
Like any modem, your Multi-Tech modem operates only under the control of a communications program, such as
the communications program included with your modem. It also operates under other general-purpose data
communication programs, such as Windows Terminal and HyperTerminal. For information on how to use the
modem with the communications program of your choice, please refer to the documentation provided with the data
communications program.
An experienced modem user can configure the program’s software to change the way the software interacts with a
modem and configure the modem to change the way it operates.
Front Panel
About the LED Indicators
The modem has ten LED indicators on the front panel that indicate status and activity:
TD
Transmit Data
Flashes when the modem is transmitting data to another modem.
RD
Receive Data
Flashes when the modem is receiving data from another modem.
CD
Carrier Detect
Lights when the modem detects a valid carrier signal from another modem. It is on when the modem
is communicating with the other modem, and off when the link is broken.
OH
Off-Hook
Lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering
a call. The LED flashes when the modem pulse-dials.
TR
Terminal Ready
Lights when a communication program is using the modem. It means the modem is ready for an
outgoing or incoming call. It goes off when the communication program disconnects the serial port.
When it goes off, a connected modem will disconnect.
Note: When you turn on the modem, the PWR indicator lights; and if a terminal program is
running, the TR indicator also lights.
Multi-Tech Systems, Inc. MT5656ZDX User Guide

Chapter 3 - Operation
Configuring Your Software
You may use either the communication program included with your modem or a third-party program.
Communication programs designed for Windows normally do not need to be manually configured, since they
obtain configuration information from Windows. Though each communication program is different, the following
procedure should work with most of them.
1. Turn on your computer and run your communications program.
2. Find the dialog box or menu that lets you select your modem. (In Windows Terminal select Settings |
Modem Commands; in HyperTerminal select File | Properties | Phone Number; and in the
communications program select Configure | General Configuration | Communication | Change
Modem.
3. Choose your modem from the program’s modem list. If it isn’t listed, choose a generic modem and modify
the settings as necessary.
4. Change the modem initialization string, if necessary. The factory default configuration works well for most
purposes. To load the factory default configuration, use AT&F. To load a custom configuration that was
saved using the &W command, use ATZ. Note that the Z command must be in a command string by
itself. For a Macintosh, the initialization string should include the &D0 command. If you do not want the
modem to always answer the phone, add S0=0 to the string. To use Caller ID with the modem, add
S0=2 to the string (Caller ID information is sent between the first and second rings, so the phone must
ring at least twice before the modem picks up the line). Depending on the software, you might have to
end the string with a carriage return character (^M).
Note: To change the modem’s default configuration, type new commands in the communication program’s terminal window, adding the &W command to store them in the modem’s nonvolatile memory. For
instance, to create a default configuration for a Macintosh computer that turns off auto answer, type
AT&F&D0S0=0&W. The new configuration loads automatically whenever the modem is turned on or
receives the ATZ command.
5. Select the port the modem is connected to (normally COM1 or COM2).
6. Select your serial port speed. This can be labeled “maximum speed,” “DTE bps,” or “baud rate.” Ideally, if
you use data compression, you should set your serial port baud rate to four times the modem’s maximum
transmission speed or faster; however, few files can be compressed enough to require speeds that high,
and not all serial ports can handle speeds that high.
7. If the communication program has an autobaud selection, make sure it is disabled. Autobaud applies only to
older modems, and can cause problems if enabled.
8. If the program allows you to edit the no-connect messages (NO CARRIER, BUSY, NO ANSWER, NO
DIAL TONE), make sure there is no space between DIAL and TONE in NO DIAL TONE.
9. Refer to the program manual or online help for other configuration choices. In most cases you can
accept the default values.
Configuring Your Modem
Your modem normally is configured through Windows or through the communication program you are using.
The default settings work best for most purposes. However, you also can configure your modem by sending
AT commands to the modem. See the AT Command Reference Guide for a list of AT (data) commands and
how to use them.

None of the LEDs light when the modem is on.
The modem does not respond to commands.
The modem dials but is unable to make a connection.
The modem disconnects while online.
The modem cannot connect when answering.
File transfer is slower than it should be.
Data is being lost.
There are garbage characters on the monitor.
The modem doesn’t work with Caller ID.
Fax and data software can’t run at the same time.
If you experience problems, please check the following possibilities before calling Technical Support.
None of the Indicators Light Up
When you turn on the modem, the PWR indicator and the terminal turn on. If the LEDs remain off, the modem is
probably not receiving power.
●
●
●
●
●
●
●
Make sure the modem’s power switch is on, especially if you normally turn the modem on by turning on a
power strip.
If the modem is plugged into a power strip, make sure the power strip is plugged in and its power switch is
on.
Make sure the transformer module is firmly connected to the modem and to the wall outlet or power strip.
If the power strip is on and the modem switch is on, try moving the transformer module to another outlet on
the power strip.
Test that the outlet is live by plugging another device, such as a lamp, into it.
The modem or the DC power transformer may be defective. If you have another Multi-Tech modem, try
swapping modems. If the problem goes away, the first modem or the DC power transformer may be defective.
Call Technical Support for assistance.
CAUTION: Do not under any circumstances replace the transformer module with one designed for another product.
Doing so can damage the modem and void your warranty.

Multi-Tech Systems, Inc. MT5656ZDX User Guide
Chapter 5 - Troubleshooting
The Modem Does Not Respond to Commands
●
Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”)
●
Make sure you are issuing the modem commands from the data communications program, either manually
in terminal mode or automatically by configuring the software. (You cannot send commands to the
modem from the DOS prompt.)
●
Make sure you are in terminal mode in your data communications program, then type AT and press
ENTER. If you get an OK response from your modem, your connections are good and the problem likely is
in the connection setup in your communications program.
●
If you don’t get an OK, the problem may still be in the communications program. Make sure you have done
whatever is necessary in your software to make a port connection. Not all communication programs
connect to the COM port automatically. Some connect when the software loads and remain connected until
the program terminates. Others can disconnect without exiting the program. The modem’s TR indicator
lights to show that the software has taken control of the modem through the COM port.
●
Your communications program settings may not match the physical port the modem is connected to. The
serial cable might be plugged into the wrong connector—check your computer documentation to make
sure. Or you might have selected a COM port in your software other than the one the modem is physically
connected to—compare the settings in your software to the physical connection.
●
If the modem is on, the cable is plugged into the correct port, the communications program is
configured correctly, and you still don’t get an OK, the fault might be in the serial cable. Make sure it is
firmly connected at both ends.
●
Is this the first time you have used the cable? If so, it may not be wired correctly. Check the cable description on the packaging to make sure the cable is the right one for your computer.
●
Peripheral expansion cards, such as sound and game cards, might include a serial port preconfigured as
COM1 or COM2. The extra serial port, or the card itself, may use the same COM port, memory address, or
interrupt request (IRQ) as your communication port. Be sure to disable any unused ports.
Windows 9x and 2000: Right-click on My Computer, select Properties from the menu, click on the
Device Manager tab, double-click on Ports, then double-click on the communication port your modem is
connected to. In the port’s Properties sheet, click on the Resources tab to see the port’s input/output
range and interrupt request. If another device is using the same address range or IRQ, it appears in the
Conflicting Device List. Uncheck Use automatic settings to change the port’s settings so they do not
conflict with the other device, or select the port the conflicting device is on and change it instead. If you
need to open your computer to change switches or jumpers on the conflicting device; refer to the device’s
documentation.
●
The serial port might be defective. If you have another serial port, install the modem on it, change the
COM port setting in your software, and try again.
●
The modem may be defective. If you have another Multi-Tech modem, try swapping modems. If the
problem goes away, the first modem may be defective. Call Technical Support for assistance.

Chapter 5 - Troubleshooting
The Modem Dials But Cannot Connect
There can be several reasons the modem fails to make a connection. Possibilities include:
●
Lack of a physical connection to the telephone line.
●
A missing dial tone.
●
A busy signal.
●
A wrong number.
●
No modem at the other end.
●
A faulty modem, computer, or software at the other end.
●
Incompatibility between modems.
You can narrow the list of possibilities by using extended result codes. Extended result codes are enabled by
default. If they have been disabled, include V1X4 in the modem’s initialization string, or in terminal mode enter
ATV1X4 and press ENTER. When you dial again, the modem reports the call’s progress.
●
If the modem reports NO DIAL TONE, check that the modem’s phone line cable is connected to both the
modem’s LINE jack (not the PHONE jack) and the phone wall jack. If the cable looks secure, try
replacing it. If that doesn’t work, the problem might be in your building’s phone installation. To test the
building installation, plug a phone into your modem’s phone wall jack and listen for a dial tone. If you
hear a dial tone, your modem might be installed behind a corporate phone system (PBX) with an internal
dial tone that sounds different from the normal dial tone. In that case, the modem might not recognize the
dial tone and might treat it as an error. Check your PBX manual to see if you can change the internal
dial tone; if you can’t, change your modem’s initialization string to replace X4 with X3, which will cause
the modem to ignore dial tones (note, however, that X3 is not allowed in some countries, such as France
and Spain).
●
If the modem reports BUSY, the other number might be busy, in which case you should try again later, or it
might indicate that you have failed to add a 9, prefix to the phone number if you must dial 9 for an outside
line.
If you must dial 9 to get an outside line, the easiest way to dial it automatically is to include it in the
modem’s dial prefix, e.g., ATDT9. Note the comma, which inserts a pause before the number is dialed. By
inserting 9, into the dial prefix, you do not have to include it in each directory entry.
18
●
If the modem reports NO ANSWER, the other system has failed to go off-hook, or you might have dialed a
wrong number. Check the number.
●
If the modem reports NO CARRIER, the phone was answered at the other end, but no connection was
made. You might have dialed a wrong number, and a person answered instead of a computer, or you might
have dialed the correct number but the other computer or software was turned off or faulty. Check the
number and try again, or try calling another system to make sure your modem is working. Also, try calling
the number on your telephone. If you hear harsh sounds, then another modem is answering the call,
and the modems might be having problems negotiating because of modem incompatibilities or line noise.
Try connecting at a lower speed.

Chapter 5 - Troubleshooting
The Modem Disconnects While Online
●
If you have Call Waiting on the same phone line as your modem, it can interrupt your connection when
someone tries to call you. If you have Call Waiting, disable it before each call. In most phone areas in North
America, you can disable Call Waiting by preceding the phone number with *70 (check with your local
phone company).
●
You can automatically disable Call Waiting by including the disabling code in the modem’s dial prefix (e.g.,
ATDT*70,—note the comma, which inserts a pause before the number is dialed). To change the dial
prefix in Windows Terminal, select Settings | Modem Commands. To change it in HyperTerminal,
select Connect from the Call menu, click Dialing Properties, check This location has Call Waiting, and
select the correct code for your phone service.
●
If you have extension phones on the same line as your modem, you or someone else can interrupt the
connection by picking up another phone. If this is a frequent problem, disconnect the extension phones
before using the modem, or install another phone line especially for the modem.
●
Check for loose connections between the modem and the computer, the phone jack, and AC power.
●
You might have had a poor connection because of line conditions or the problem might have originated on
the other end of the line. Try again.
●
If you were online, it might have hung up on you because of lack of activity on your part or because you
exceeded your time limit for the day. Try again.
The Modem Cannot Connect When Answering
Autoanswer might be disabled. Turn on autoanswer in your data communications program or send the
command ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.
There Are Garbage Characters on the Monitor
●
Your computer and the remote computer might be set to different word lengths, stop bits, or parities. If you
have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communications program.
●
You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call
again; you might get a better connection the second time.
●
Try entering the &V1 command to display information about the last connection, making a screen print
of the connection statistics, and checking for parameters that might be unacceptable.
The Modem Doesn’t Work with Caller ID
●
Caller ID information is transmitted between the first and second rings, if the modem is set to answer after
only one ring (S0=1), the modem will not receive Caller ID information. Check your initialization string, and
if necessary change it to set the modem to answer after the second ring (S0=2).
●
Make sure that you have Caller ID service from your telephone company.

Appendix C – Upgrading the Modem
Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory.
Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However, it can be
changed by either the manufacturer or the user.
Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few minutes by
using the following procedures.
Upgrade Overview
The upgrade procedure consists of the following steps, which are described in greater detail in the following
sections.
1. Identify the model number and firmware version of your modem.
2. Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has the
current firmware, there is no need to update it.
3. Download the upgrade file for your modem.
4. Extract the firmware .HEX file and the appropriate flash upgrade program from the file you downloaded.
5. Document and clear your stored parameters.
6. Upgrade the modem’s firmware using the .HEX file and the flash upgrade program.
7. Restore your parameters.
Step 1: Identify the Modem Firmware
You must know the model number and firmware version of your Multi-Tech modem to know whether or not
you should update it.
1. Run your favorite terminal program. If you are using Windows 95, 98, 2000 or Windows NT, you can use
HyperTerminal. If you are using Windows 3.1, you can use Windows Terminal.
2. In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your screen,
be sure to type it completely, and then press ENTER. If the modem does not respond with OK, repeat
the AT&F command.
3. Now type ATI3 and record your results. The firmware version should appear first in the response, which
should look similar to the following:
V2.300G-V90_2M_DLS
Step 2: Identify the Current Firmware Version
Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has the current
firmware, there is no need to update it.
Using your favorite Web browser, go to http://www.multitech.com/en_US/SUPPORT/Updates/drivers/
Scroll down the table to your modem model number.
Look at the firmware version number for your modem.
If the firmware version number matches the firmware version number found in “Step 1: Identify the Modem
Firmware,” your modem has the current firmware version, and does not need to be updated.
5. If the firmware version number is greater than the firmware version number found in “Step 1: Identify the
Modem Firmware,” your modem has an older firmware version.
Continue with “Step 3: Download the Upgrade File.”
1.
2.
3.
4.
Warning: The first digit of the new firmware must match the first digit of the old firmware, or the modem may not
work properly; e.g., if your current firmware version is 4.16, replace it only with 4.xx firmware, not 6.xx firmware.
Multi-Tech Systems, Inc. MT5656ZDX User Guide
23
Appendix C – Upgrading the Modem
Step 3: Download the Upgrade File
1. If you are not already at the MultiModemZDX firmware page of the Multi-Tech Web site, follow the procedure in “Step 2: Identify the Current Firmware.”
2. Download the upgrade file for your modem by clicking its name, and save the file in a temporary folder on
your hard disk.
3. In the same section of the Web page, download the Flash Wizard utility for your operating system by
clicking it, and save it in the same folder.
Step 4: Extract the Upgrade Files
1. Install the Flash Wizard utility by double-clicking the file name in Windows Explorer.
2. Extract the upgrade files by double-clicking the file name. The extracted files include a .HEX file, which
contains the upgrade data, and a Readme file.
3. Copy the upgrade .S37 file into the Flash Wizard folder.
Step 5: Upgrade the Modem’s Firmware
Before you begin the following procedure, read the README.TXT file extracted from the upgrade archive file. Note
the file name for the boot code (e.g., 2MBPFL1 1 .S37) and the file name for the new firmware (e.g.,
BkQg300G.hex).
Warning: Never install an older version of firmware over a newer version. Doing so will destroy the Flash
PROM! If the Flash PROM is destroyed, the modem must be sent in for repair.
1. Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the Start menu. The
Identifying Devices dialog box is displayed as Flash Wizard locates and identifies the devices connected
to your system.
Note: If the message ERROR: No valid devices detected is displayed, verify that the device is powered on
and that all cables are correctly and securely attached.
2. Click the modem to be upgraded, and then click Next to proceed.
3. Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex File list, and
then click Next to continue.
Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.
4. The Progress dialog box appears, showing a status bar that indicates the progress of the upgrade.
Caution: Any disruption of the program during this stage of the upgrade can cause your modem to become
inoperable. Wait for the Next button to become active before proceeding.
5. When the flash upgrade is complete, the message Programming Complete appears. Click Next to
continue.
6. The Results dialog box appears next. Click Finish to exit Flash Wizard.
Step 6: Restore Your Parameters
Your modem has been updated. You can now open your terminal program to reprogram your modem
parameters or to confirm the update by typing ATI3 in the terminal window and pressing Enter.
